To evaluate the variation of serum IGF-1 levels during GH replacement and observe gender differences, 29 adults with GH deficiency (mean age 42.5 +/- 10.1 year), were studied. Serum IGF-1 was assessed every 4 weeks during the titration period and afterwards every 3 months of GH therapy. At baseline 77.7% of women and 45.4% of men had serum baseline IGF-1 levels below the lower limit of normal age-related reference range. The time to reach the maintenance dose was lower in men than women (p < 0.05). There was an increase in IGF-1 levels after one year of GH therapy, significant only in men (p < 0.01). IGF-1 concentrations were higher in men than women (p < 0.05), at the 12th and 18th months of GH therapy. GH dose was reduced by 25% in men (p < 0.01). At the end of the study the mean GH dose was lower in men than in women (p < 0.05). The factor responsible for these findings is not known, however a possible role of androgens has been suggested.

The paradoxical GH response at OGTT does not predict Pasireotide efficacy but matters for glucose metabolism.
J Endocrinol Invest

Department of Medicine (DIMED), University of Padova, Padua, Italy.
Purpose: A paradoxical increase in GH after oral glucose load (GH-Par) characterizes about one-third of acromegaly patients and is associated with a better response to first-generation somatostatin receptor ligands (fg-SRLs). Pasireotide is typically considered as a second-/third-line treatment. Here, we investigated the predictive role of GH-Par in pasireotide response and adverse event development.

J Pediatr Endocrinol Metab

Objectives: The gonadotropin-releasing hormone (GnRH) provocation test is crucial for diagnosing central precocious puberty (CPP). However, due to its invasion and high cost, it is essential to find a simpler biomarker. This study aimed to investigate the feasibility of fasting insulin (FINS) and insulin-like growth factor-1 (IGF-1) as potential biomarkers for diagnosing girls with CPP and to analyze their effects on puberty development.

Department of Radiology, The First Affiliated Hospital, Sun Yat-sen University, Guangzhou, China.
Background: Pediatric growth hormone deficiency (GHD) is a disease resulting from the impaired growth hormone-insulin-like growth factor-1 (GH-IGF-1) axis, but the effects of GHD on children's behavior and brain microstructural structure alterations have not yet been fully clarified. We aimed to investigate the quantitative profiles of gray matter and white matter in pediatric GHD using synthetic magnetic resonance imaging (MRI).
Methods: The data of 50 children with GHD and 50 typically developing (TD) children were prospectively collected.
Effect of selenium on the dysfunction of rat salivary glands induced by 131I and expression of insulin-like growth factors and aquaporins.
Nucl Med Commun
January 2025
Department of Nuclear Medicine, First Hospital of Shanxi Medical University.
Objectives: To investigate the effects of selenium on functional and histopathological changes and mRNA expression levels of insulin-like growth factors 1 and 2 (IGF-1 and -2) and aquaporins 4 and 5 (AQP-4 and -5) in 131I-induced damaged rat parotid glands.
Methods: Rats were divided into three groups: iodotherapy-with-selenium, iodotherapy-only, and control. Rats in the iodotherapy-with-selenium group were intragastrically administered 131I on the first day and selenomethionine through drinking water.
Obesity increases DNA damage in the breast epithelium.

Obesity is a modifiable risk factor for breast cancer. Yet, how obesity contributes to cancer initiation is not fully understood. The goal of this study was to determine if the body mass index (BMI) and metabolic hallmarks of obesity are related to DNA damage in normal breast tissue.
